To'all whom it ina'y concern:

Be it known that I, CARL WALTER GE- BAUER, girdler, subject of theKingpf Sa-X- ony, residing at Dresden, Germany, have in vented certainnew and usefulv Improve@ ments in Shells forArtillery, of which thefollowing is a specication.`

This invention relates to a shell for 'use any caliber vand is soconstructed dition to the ordinary. spreading eect similar to shrapnelproduced only when it bursts, it ca-uses elongated bullets to bedischarged at intervals as desired at an. obtuse angle in relation tothe direction of its Hight, so that it is possible to ,reach an enemywho is under of a special arrangement.

1". In Sheets I, II and III of the accompany-l ing drawing theconstruction of a shell ac base of the shell, 11 is 'a transverse seo.

cover-: this being lrendered possible by means the projectile anydesired number of elongated bullets are obliquelyarranged in such amanner that they lie' atan acute angle in relation tothe axis ofthe-hollow s hell and can be discharged from the latter during itsflight bymeans of special ignition devices at an acute angle in theopposite direction to the'line of ight.

cording to the present invention is illustrated.

- Figure 1 is a longitudinal .section of the shell, Fig. 2 is anelevation, Fig. 3 isa longitudinal section of the head of the shell,Fig. 4 is a cross section thereof, Fi 5 is a plan of the timing disk,Fig. 6 is an inverted` plan of the same, Fig. 7 'is a section of thesame, Fig. 8 is a plan of'- the adjusting ring by means of which the-timin the same, Fig..10^is a sectional view of the tion through theshell.

chambers 2, 3,4, 5 (Figs. 1 and 11) open- In the interior of the's'hellisa cylindrical chamber-1, which is ,filled with explosive material, andinto which four trapezoid like whic are intended for the reception ofthe shrapnel shot'. Between the chambers 2 to 5 are partitions 7 (Fig.11) 'which extend inward up to the cylindrical chamber 1 and form awhole-With the shellcasing-G. In'

the casing 6 extending into the partitions 7 are holes 8 for thecartridges 9 which are suitably screwed int-o the same, These holes 8Whichform an acute anglewlth the axls of the shell are -connectedbymeans of small -ably provided for the fuses. may .be of that in ad,

In the case` of of the ignition can be regulated, Fig. 9 1s a section of(F ig. .1) running through the .shot 41n the partitions 7. To the sideof the. passages 11 forward passages -10 with longitudinal passa-gesl11.-

of the rows of projectiles, that is in the -cas-` ing 6 which .isreinforced by partitions 7 two 'longitudinal cylindrical borings Y12aresuitg formed by a longitudinally drilled Weight 13, the hole in whichis Venlarged rearwardly at 14 for receiving a detonator. On' the bot#tom of the hole 12 a pin 15 is arranged from The latter are which theweight is held apart by a 'spring' 16 igs. l and, 3).' The hole 12 isclosedby a drilledserew disk 17 which extends by mea-ns of a small tube18 into the holein the weight and acts as a' guide to the latter.

In the hole in the weight 13,- and in the tube 18 as well as in thepassages 10 -and 1 1, a suitable4 fuse, powder is placed. 'When theshell. is i'red, the weights 18 with thedetfy onatorsmove sharplyagainst the pin' 15 in consequence of their inertia, the power of .thespring 16 beingfovercome, and the fuse powder in the passages which leadto the rcartridges being ignited and the bullets dl'scharged (Fig. 3).

vI n order that the ignition for the elongated bulletsmay be adjusted toany de sir'ed distance the 4following arrangement is made. The timingdisk 19 illustrated .in

Figs. 45, 6. and `7 is screwed. by means'of its,

screw piece 20 into thel screw thread 21 formed in the shell'in such a.manner that the borings- 22 therein come exactlyover the ignitionopenings 23 or` communicate therewith (Fig. 1). On the rear faceof ,thisdisk is a circular groove 24,.wh1ch 1n turn stands over t-he passages 1lin the casinward, the-.onethrough the boring ,240i the timing disk 19 isdrilled throughl obj liquely rearward in order to meet the groove 24..VIn front of the timing disk 19 the ad,-

justingdisk 25shown in Figs. 8" and 9Y is' screwed on to the innercylindrical jpalt 26 of the shell (Fig. 1).. This disk isjf ormed withthrough passages 27 and 28,/a'ndwit-h two grooves 29 and 30 which break'the cir so. A

ing.' .As the one fuse is placed somewhat cleat places situated opposite'oneanothen The passages y27 and 28'are connected by. tangentialfgrooves31. The .passages 27 are somewhat oblique and run into the groove 24 ofthe? timing disk. The through .borings 27 open into the'v groovesv 24m241"v rovided o n theforward face-of the timing isk and thenceinto thegroove 24 inthe rear face..

Alligrooves and passages are filled w-ith fuse. v powder.` Between thegrooves circular ribs 32 are formedon the one hand and recesses 33 onthe other hand, so that the filled ignition passages cannot communica-tewlth one another in any` unintended manner owing 'through horings 22 inthe fuse regulating disk, the quickest time for ignition 'for theprojectiles t) is at a distance of 500 meters, .because in this case theflashing of the ignA ting massis only effected 'throughthe ltang ntialpat-h 31 to thefvertical passages l1. If on the other ha nd the diskQ beadjusted so thatfthe through bori'ngs-QQ -in the timing disk communicatewith the ends of the grooves 29 and 30, the explosion of the projectileis longest delayed, because the ign-iting substance must firstburn awayin the grooves before there is any ignition of what is in the grooves31; Consequently the eX- plosionl lonly takes place at a dist-ance of8,000 meters. Accordingly as the through passages 22 in the' timingdisk19 are more or lessdistant from the through boringsI .28 andthetangential grooves 31 run into the grooves 29 and 30', the earlier orthe later will the projectile 9 Aarranged in the casing be ignited;Ifthe adjusting disk be so adjusted that the places where the grooves 29and BOnreinterrupted come over the through borings 22, the path ofignition is shut off there and no ignition of the projectile can occur.It is advisable to effect this adjustment 'when the shot is removedfrom'one place to another.

The effects of the shell are once more briefly summarized. Vhen theshell is discharged the fuse powder inthe ignition weights is ignited bythe return action on the head placed on the detonating cap. kTheignition proceeds through the ignition holes in the-disk, and thepassages in the adjusting ringtilled with fuse powder and thence throughthe inner ignition holes or ignition grooves in the disk, reaching thepassages 11 in the cartridges and causing these latter `to explode.According to the adjustment of "the timing ring or according to thelength of the path of ignition in the grooves of the timing ring theelongated bullets are disvcharged 'at certain times and places, the

greatest and smallest adjustment of the timing ring in regard to theperiods of eX- plosion of the elongated bullets varying betweendistancesof 500 and 8000 meters. A

-bullets in meters.

scale which is arranged on the periphery of the timing ring indicatesthe time to be adjusted for'the explosion. of the elongated Moreover thedead position of the timing ring in which the ignition passages areclosed and no explosion can occur even if ignition Vtake place is shownon the scale. Thus the cartridges can be tired at a determineddistaneeand time. By the firing of the cartridges enemies -even undergood cover in trenches can be reached;

while the shot itself hasa greater range through the reaction of thebullets. The. bursting of thefshell and the spreading of Vthe round shotcan be adjusted by the timing disk independently of theV firing of thecartridges owing tothe number of borings in the casing .the latterbursts into a much larger number of small parts, than hitherto, and thusinsures a powerful explosive effect.

Having now particularly described and ascertained the nature of thisinvention and in what manner the same is to be performed,v

I declare that what I claim is- 1. The combination with an artilleryshell having a plurality of longitudinal shrapnel chambers andpartitions separating the chambers, of a plurality o f projectilesfitted in each partition.

2. The combination with an artillery shell having a plurality oflongitudinal shrapnel chambers and partitions lseparating the chambers,of aplurality of projectiles fitted in each partition, and meansindependent of the explosive in the shell for tiring the projectiles. Y

3. The combinatign with an artillery shell having a plurality oflongitudinal shrapnel chambers and partitions separating the chambersand each having a longitudinal powder duct, of a plurality ofproject-iles fitted in each partition and tired by the eX- plosion ofthe powder in each ducta detonator, and means for transmitting the Hashfrom the detonator to the powder ducts. 4. |Ihe combination with anartillery shell having a plurality of longitudinal shrapnel chambers andpartitions separating the chambers and each having a longitudinal powderduct, of a plurality of projectiles fitted in each partition and tiredby the explosion of the -powder in each duct, a detonator, and means fortransmittingv the flash from the detonator to the powder ducts,consisting of an adjustable part by means of which the length of thepath ,of

transmission between the detonator and the powder ducts may be varied.
